Perform this configuration on the PEs. Only conventional RIP is required on CEs.

After configuring a RIP instance, you must start RIP by using the same method for starting a
common RIP process.

Configuring OSPF between PE and CE

An OSPF process that is bound to a VPN instance does not use the public network router ID
configured in system view. Therefore, you need to specify the router ID when starting a process or to
configure the IP address for at least one interface of the VPN instance.

An OSPF process belongs to only one VPN instance. If you run an OSPF process without binding it to
a VPN instance, the process is considered a public network process.

Follow these steps to configure OSPF between PE and CE:

To do…

Use the command…

Remarks

Enter system view

system-view

Create an OSPF instance between

PE and CE and enter the OSPF

view

ospf

[ process-id | router-id

router-id

| vpn-instance

vpn-instance-name

]

Required

Configure the OSPF domain ID

domain-id

domain-id

[ secondary ]

Optional

0 by default

Configure the type codes of OSPF

extended community attributes

ext-community-type

{ domain-id

type-code1

| router-id type-code2

| route-type type-code3 }

Optional

The defaults are as follows:

0x0005 for Domain ID,

0x0107 for Router ID, and

0x0306 for Route Type.

Configure this command on a PE.

z

Perform the configurations on PEs. Only conventional OSPF is required on CEs.

z

Deleting a VPN instance will delete all related OSPF processes at the same time.

An OSPF process can be configured with only one domain ID. Domain IDs of different OSPF
processes are independent of each other.
